Edit:
Guaranteed to be from Hugen, perhaps bought through his site at

The problem with Amazon carrying them is their markup. When I was looking at the RSP Duo it was 30.00 more from HRO through Amazon than direct from their website. I wanted to use them as I had a credit. I reached out to HRO about it and they told me it was due to their fees which apparently are obscene.

Amazon does charge high fees, but you get the advantage of a 2 week no
question return policy. By the as a former small business owner I would not
sell through Amazon because of the mark up.

Thank You!

Almost everything on Amazon is more expensive due to those fees. That's how Bezos is one of the richest men on earth.? My wife has prime and every time she offers to buy something I want a quick search finds it for less.? The "free" shipping is because they include it in the price then mark it up.? I'm also surprised how many items don't "qualify" for free shipping.? There are quite a few items where it is cheaper to buy locally!? Which I prefer anyway.

P/S., I might want a couple more of these things to play with and would prefer to buy from the person who made them possible.

I pulled the triggger, buying from Hugen's friend on Alibaba.
Cost of $60 plus $1.70 to Alibaba for the Mastercard transaction fee.
Seems plenty fair, especially considering all the trainwrecks they would see
when shipping to random people half a world away.

tabaoFOCUS might work, a little cheaper, seems a bit higher risk.

Perhaps someone in the group could buy in the batches of 50 for $35 each,
charge $60 via paypal, distribute them locally.

Hello Jerry,

I bought a nanoVNA from Banggood many weeks ago.
There was an order row also indicating prices.
My order was in the low 100 and price was low ;
The number row went up to 700+ with a price around $60;
I had to wait for the usual delay but I received the complete package ; VNA +2cables + 1 through SMA+open+Load +short+usb cable.
It seems the original nano ;black with shields,two red leds.
On switch on it displays : nanoVNA---- GEN111.tabao.com .
There was no bat but I found one at Alieexpress as mentioned in the group here.
4 traces soft was loaded, 50KC to 900MHz,broadband calibration was ready.
Works perfect also with the PC Sharp soft V1.03 under Windows 10 and I can export Sparameters to other programs.
I compared only passive circuits until now and they confirm with my HP8753ES( of course not the same dynamic range )

At banggood nanoVNA now is a new batch at $60 in the mean time.
Lot of info also published is the group is on the site and also a link to the soft.

I am very happy with it although it is very fragile and far from" student-proof". Of course some extras would be very welcome.
I just think Banggood is reselling it for Tabao;

I just bought one from Hugen's Alibaba friend(s), using paypal direct to the sellers job email.
Should be here in about two weeks. We'll see, 60usd is a low enough stake for a gamble.

That friend seems to be a well established wholesale operator which is probably why lots of 50 are so much cheaper than singles.

Good to hear that you are happy with what you got from Banggood.
Would be interesting to know if the internal construction agrees with these photos:

On switch on it displays : nanoVNA---- GEN111.tabao.com .

That may not mean much.
I suspect all of the clone makers are just burning Hugen's binaries.

I've heard the jog switch is fragile, but that would be easy to replace
with most any momentary SPDT toggle switch, or perhaps two SPST push-buttons.
If you need durability then maybe set the whole thing in a box,
give it a larger top plate fabbed from FR4, place the SMA's hard against
one end of the box, could use an extension on the USB connector.

Or just buy 10 of the nanoVNA's off of Alibaba, go for redundancy instead.


From /g/nanovna-users/message/367

I am trying to improve nanovna to provide better performance, try to make a more reliable shell
for everyday use and international shipping.Maybe I can finish this work in October. hugen

Any thoughts from the group on how best to defeat the next round of clones?
Perhaps the existing code remains open source on a small ARM uC,
but a second uC with firmware enhancements gets locked down?

I just received mine from this ebay seller:



The product arrived in 3 or 4 days and is the shielded unit. Works as
advertised.

I thought to take a chance as the long wait for a China shipment was, for
once, not desired.

Just FYI.

I purchased one from this seller last month, $49 shipped! He's sold about 15 just this month so I dont think he will go too low on his best offer now since everyone wants one lol So far I am happy with it except my eyes wish the screen was 4 times bigger lol. I roughly get about 2.5hrs before needing recharge and only done this twice. The 2 jumpers that came with it are ok but go bonkers above 700MHz. The 50 Ohm load looked ok when I measured it with my Agilent 8712ES. I am a little confused with the "open" OSL that came with it, it's missing the center pin which means that there is no L or C to take into account for an "open" connector. For stuff in the HF range probably has no effect but I would think it would start having effects VHF and above? I WISH the unit would power up from the point that it was when it was powered off. It also resets itself whenever you pull out the USB connector and it switches to it's internal battery, not sure if this "normal" or not.? As time and health permit I will run some real world test with this little guy and post my results.

I orderd it off alibaba with a $60 usd charge with shipping referring it to
a Hugen
$2.50 for the credit card transaction with a 3-10 day delivery

lets see how it goes

I just ordered a nanavna from Alibaba Wuyi Zeenko Industrial And Trading Co., Ltd.(the Hugen design based on edy555).

Thx to all for info on “place to buy”.

Henry

This seller was pretty quick and packaging was done with great care. Mine was packed in anti-static bag layed over a foam deposited in a aluminiun tin can wrapped in bubble then in envloppe....(the tester where in a separate bag cable and the two cable layered under the foam.)

Today's TomTop.com specials includes what appears to be Hugen's version of the nanoVNA.
It's on sale for a tad over $42 US. with FREE shipping

I've ordered from TomTop many times without issue but it is essentially similar to eBay/Aliexpress/Banggood/etc - an umbrella for many sellers.
YMMV

The referenced tomtop sell price seemed like a good deal until I noticed in the specification list that a battery is not included.

!!@%$*^(#!!
Sorry, didn't see that.
Well, you can always order form the guy several of us on the forum bought from: Guangyi0016 on Aliexpress
Good service and Hugen's version, WITH battery and shields.

Transporting lithium ion batteries legally is not easy. Of course, a lot
of the sellers don’t worry about that sort of thing.

Obviously the seller stole my product picture, but in the sale of inferior clones, I am very disappointed.

I bought this one from eBay:

Item ID: 233265098213

Seller ID: sqcase

because it was a UK source (Birmingham) but as it had no shield (and was described as having such) I sent it right back. Waiting for my eBay refund.

I'll stick with my FA VA5 instead.

Cheers,
David

Hi all,

Seems I've ordered the same item (due next week), but there was no mention
of shielding in the description when I ordered it!

For testing homebrew antennas I'm not concerned; Considering some
comparisons with my club's MFJ and Rigexpert analysers further down the
line.

Cheers, Merlin M0MFX
